viremia/diarrhea

Virus isolation and serum neutralizing antibody titers were determined over a period of time from samples collected from animals persistently infected with bovine viral diarrhea virus (BVDV). To evaluate over time the ability to detect BVDV by virus isolation from serum or white blood cell

In order to determine whether elk (Cervus elaphus) could be infected with and shed bovine viral diarrhea virus (BVDV) and to determine whether BVDV could cause disease in elk, two groups of five yearling elk each and two control cattle were experimentally inoculated intranasally with type 1 Singer

OBJECTIVE To evaluate the efficacy of 4 commercially available multivalent modified-live virus vaccines against clinical disease, viremia, and viral shedding caused by bovine viral diarrhea virus (BVDV) and bovine herpesvirus 1 (BHV1) in early-weaned beef calves. METHODS 54 early-weaned beef steers

OBJECTIVE To compare degree of viremia and disease manifestations in calves with type-I and -II bovine viral diarrhea virus (BVDV) infection. METHODS 16 calves. METHODS Colostrum-deprived calves obtained immediately after birth were assigned to 1 control and 3 treatment groups (4 calves/group).

OBJECTIVE To test the hypothesis that viremia might be involved in infants with rotavirus (RV) diarrhea and extraintestinal infection. METHODS The genomes of RV in the plasma of 60 infants with RV diarrhea were detected with nested reverse transcriptase-PCR, which were also performed on the

Recently, in the United States, a dairy bull was diagnosed as the second confirmed case of persistent testicular infection (PTI) with bovine viral diarrhea virus (BVDV). The first objective of this study was to evaluate the testing methodologies currently used by the artificial insemination industry

OBJECTIVE To evaluate persistence of bovine viral diarrhea virus (BVDV) in semen after inoculation of postpubertal bulls. METHODS Three 2-year-old bulls and five 6-month-old calves. METHODS 3 seronegative 2-year-old bulls were inoculated intranasally with BVDV. Serum and semen samples were obtained

BACKGROUND Substantial bovine viral diarrhea virus (BVDV)-related production losses in North American alpaca herds have been associated with BVDV type Ib infection. OBJECTIVE To classify and differentiate the long-term clinicopathological characteristics of BVDV type Ib infection of alpaca crias,

The aim of this study was to determine the pathogenicity of an Indian bovine viral diarrhea virus (BVDV) 1b isolate in 7-9-months-old male calves. Infected (four) and control (two) calves were bled at three days interval for hematological, virological and serological studies until day 27. All

A new genotype of bovine viral diarrhea virus (BVDV), designated BVDV type 2 (BVDV 2), has become prevalent in the field. BVDV 2 strains are antigenically distinct from currently available vaccine strains of the BVDV 1 genotype, raising concerns about cross-protection of these vaccines against BVDV

OBJECTIVE To study the incidence of viraemia and extraintestinal organ damage in children with acute rotavirus (RV) gastroenteritis. METHODS Eighty-three children with acute rotavirus gastroenteritis were hospitalized from October 2002 to March 2003, whose blood and fecal samples were obtained on

OBJECTIVE To evaluate onset of protection induced by modified-live virus (MLV) bovine viral diarrhea virus (BVDV) vaccine administered 7, 5, or 3 days before inoculation with type 1b BVDV (strain NY-1). Animals-40 calves. METHODS Calves were assigned to 4 groups: an unvaccinated control group or

Bovine viral diarrhea virus (BVDV) with deletions in the 5'-nontranslated region (5'-NTR) were tested for their suitability as live BVD vaccines. Firstly, the genetic stability of the mutants was established by culturing over 15 passages in bovine cells. Secondly, two deletion mutants and the parent

Rotavirus infection is usually localized to the intestine but involvement of extra-intestinal sites, including the respiratory tract, liver, kidney, lymph nodes, and central nervous system, has been reported. The extra-intestinal spread of the virus may occur through blood since viraemia has been
